Abstract
Sulfoquinovosyldiglyceride and triglycosyldiglyceride were isolated from rice grains, mainly by column chromatography and thin-layer chromatography. The major component fatty acids were palmitic, oleic, stearic and linoleic acids in sulfoquinovosyldiglyceride whereas they were linoleic, palmitic and oleic acids in triglycosyldiglyceride, in decreasing order of amount. The component sugar in sulfoquinovosyldiglyceride was sulfoquinovose, while those in triglycosyldiglyceride were galactose and glucose, the latter being predominant.
